Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758228, here are decompositions:

29 + 8758199 = 8758228
41 + 8758187 = 8758228
71 + 8758157 = 8758228
179 + 8758049 = 8758228
419 + 8757809 = 8758228
509 + 8757719 = 8758228
569 + 8757659 = 8758228
659 + 8757569 = 8758228

Showing the first eight; more decompositions exist.
